Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

• Resistance Value: 2.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Dimensional variations within the 2512 package specification are acceptable for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RMCF2512FT2K10 (Stackpole Electronics Inc) is the preferred substitute. This part maintains Active product status, carries AEC-Q200 automotive qualification, and has the highest inventory availability (9001 pcs). Dimensional specifications are identical to the main part.

Secondary Selection: AC2512FK-072K1L (YAGEO) is an acceptable alternative with Active product status and AEC-Q200 qualification. Inventory availability is substantial (3986 pcs). Minor dimensional variation exists within package tolerance (length 6.35mm vs. 6.30mm, height 0.65mm vs. 0.66mm).

Legacy Selection: ERJ-1TNF2101U (Panasonic Electronic Components) carries AEC-Q200 qualification but is marked "Not For New Designs." This part is suitable only for replacement or maintenance applications in existing designs. Inventory is available (4723 pcs).

All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-072K1L replace RC6432F2101CS in new designs?

A: Yes. AC2512FK-072K1L meets all electrical and mechanical specifications. Dimensional variation (length 6.35mm vs. 6.30mm, height 0.65mm vs. 0.66mm) remains within 2512 package tolerance and does not affect PCB assembly compatibility.

Q: Why is ERJ-1TNF2101U marked "Not For New Designs"?

A: This designation reflects the manufacturer's product lifecycle status. The part remains functionally equivalent and suitable for replacement applications but should not be selected for new circuit designs.

Q: Are all substitute parts automotive-qualified?

A: AC2512FK-072K1L, ERJ-1TNF2101U, and RMCF2512FT2K10 carry AEC-Q200 automotive qualification. RC6432F2101CS does not specify automotive qualification in the provided data.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Are there dimensional constraints for PCB layout?

A: All parts conform to the 2512 (6432 Metric) package specification. Maximum dimensional variations are: length 6.30-6.40mm, width 3.10-3.20mm, height 0.65-0.70mm. Standard PCB footprints accommodate these tolerances.

Q: Do all parts share identical HTSUS and ECCN classifications?

A: Yes. All parts are classified under HTSUS 8533.21.0030 and ECCN EAR99, ensuring consistent regulatory treatment for procurement and export purposes.
